CITY OF GARDEN CITY

Standards for Excavations

In

Public Rights-of -Way

1. EXCAVATIONS

A. General

1. Only General Contractors or Plumbing Contractors, Telecommunications/Video Service

Providers, or Franchised Utilities are permitted to perform excavations within the public

rights-of way. Before making any excavation, demolition, patch, stockpile, or other

improvement within the public rights-of-way, an Excavation permit shall be obtained from

the City Inspection Department.

If there is an emergency necessitating response work or repair, any utility, which has been

granted permission to occupy the public right-of-way, may begin that repair or emergency

response work or take any action required under the circumstances, provided that the utility

notifies the city promptly after beginning the work and timely thereafter meets any permit

or other requirement had there not been such an emergency.

2. Permit holder shall be responsible for locating utilities before excavation begins, utilizing

the Kansas One Call “811” system. The City of Garden City is not responsible for damages

to utilities caused by the Permit holder.

3. Inspections: When inspections are required, the Permit holder shall contact the City Office

during normal office hours. A 24-hour advance notice is requested. The Inspector will

respond as quickly as possible. A job foreman, authorized to act on behalf of the Permit

holder, shall be present during the inspection. If any work is not approved, the Permit

holder shall correct the deficiency and reschedule the inspection. Approval does not limit

the Permit holder’s responsibility to meet these standards; or extend any warranty to the

permit holder, owner, or others about the workmanship, methods, or equipment used; or

waives the City’s right to enforce these standards if work previously approved is

subsequently proven defective.

4. Where utilities cross under state highways, county roads or railroads, the requirements of

those agencies shall also be met and applicable permits shall be obtained and displayed

before construction begins. Permit holder shall provide copies of such permits to the City,

if requested.

5. Utility mains shall be located within alley rights-of-way and public easements as shown in

Section III. Deviation from standard locations requires approval by the Public Works

Department. Utility main locations within street rights-of-way shall be subject to approval

by the Public Works Department.

General Improvements Handbook (2017) Page 5 of 108

Page 6: GENERAL IMPROVEMENTS HANDBOOK - Garden City

6. The permit holder shall maintain all gutters, and other drainage facilities of the city, free

and unobstructed for the full depth of the adjacent curb and for at least two feet from the

face of the curb at any gutter.

7. The permit holder shall be required to take measures to protect the storm sewer system

from excessive contamination from permitted activities.

8. The permit holder shall be required to take measures to protect the sanitary sewer and water

systems from contamination from permitted activities.

9. Excavations within or in close proximity of street or alley improvements may be required

to be loosely backfilled, to prevent damage to the street or alley improvement from cave

ins, overnight or during periods of no activity.

B. Traffic Control (Barricades, Warning Signs, and Lights)

Temporary traffic control is the responsibility of the permit holder/contractor. The permit

holder/contractor shall submit a plan to the Public Works Department for review. The

temporary traffic control shall conform to Part 6, Temporary Traffic Control, of the latest

edition of the Manual of Uniform Traffic Control Devices (MUTCD).

C. Trenching

The Permit holder is reminded of Federal regulations governing trench safety and confined

space entry. Permit holder shall protect existing utilities and services and existing underground

or surface improvements including, but not limited to, buildings, foundations, curbs, side-

walks and pavements, plantings, irrigation lines, utility poles, and light poles. Protective

measures may include underpinning, shoring or other bracing. Permit holder shall repair or

replace existing improvements damaged by construction work.

D. Boring/Directional Drilling

Utility placement by boring, or directional drilling, shall be approved by the Public Works

Department prior to the issuance of a permit. The Director of Public Works may require

references or a test bore to demonstrate the ability of the equipment to hold the line and grade

for the proposed distance.

E. Plowing

Plowing is an acceptable method for installing buried cables, but extreme caution should be

used. All plowed cables shall be placed in a straight line parallel with the other utilities. When

crossing rights-of–way, buried cables must be within 10º of perpendicular to the right-of –way.

The following depths must be met when burying cables:

1. Public Rights-of Way shall be 24 inches in depth, see Drawing No. I-1.

2. Carry 12 inches depth into private property for a minimum of 10 feet.

General Improvements Handbook (2017) Page 6 of 108

Page 7: GENERAL IMPROVEMENTS HANDBOOK - Garden City

F. Initial Pavement Cut

1. Cut the existing pavement in straight, parallel lines, using a saw, air hammer or other

approved method and carefully remove the material so as not to disturb the adjacent

material.

2. After utility work is complete, and the trench has been backfilled, make the final

pavement cut as specified in Section I.2.A.2 of these regulations. At the Permit holder’s

option the initial pavement cut may be made to the standards of the final pavement cut;

care must be taken to avoid sloughing of the sub-grade shoulder.

G. Trench Backfill

1. Permit holder shall contact the Public Works Department or Inspector prior to the work

to determine the backfill requirements for the specific location.

2. Earth backfill, if allowed, shall be brought to satisfactory moisture content during placing

as required by the Public Works Department or Inspector. After placing, the material

shall be firmly and satisfactorily compacted. The Public Works Department or Inspector

will determine by visual inspection that satisfactory compaction is being obtained. If the

backfill fails these requirements, the Permit holder shall be required to remove and

replace the backfill and pay for testing.

3. If the trench extends into private property, the Permit holder shall compact the trench 10

feet into the private property according to these specifications.

4. Only mechanical rammers or tampers shall be used for compaction. Plate vibrators may

be used for sand backfill. Water settlement (compaction) by flooding or puddling, is not

allowed. Plate vibrators or other compaction equipment and methods are allowed only

if the permit holder provides, at his expense, satisfactory compaction test results at

subgrade and at a depth of one foot below subgrade.

5. The Public Works Department may require as a condition of the permit, the Permit holder

to compact the trench backfill to a density of not less than 95% maximum density as

determined by ASTM D698. Permit holder shall be responsible for providing the City

with maximum density – optimum moisture content test data (Proctor test) on the subject

backfill. Permit holder may also be required, as a condition of the permit, to provide

compaction testing reports, prepared by an independent testing company, at specified

frequencies.

General Improvements Handbook (2017) Page 7 of 108

Page 8: GENERAL IMPROVEMENTS HANDBOOK - Garden City

6. Flowable fill may be required when working in paved streets and to 12 inches behind the back of curb or edge of pavement for trench backfill. Most utilities will require common earth material between the utility and the flowable fill. No more than 12 inches of dirt above the utility shall be used unless otherwise approved by the Public Works Department. Flowable fill material shall meet the requirements of City Standard Specifications, Section Str-6, Concrete Mixtures. Care should be taken to secure the utility in the trench so that the pouring of flowable fill will not cause the utility to float toward the surface.

7. Backfill material for excavations in other than paved streets and buffers below flowable

fill shall consist of approved imported material or approved earth material from the excavation. Backfill shall be free from trash, lumber, construction debris, wet or frozen material, and excessive amounts of organic matter. Highly plastic clay shall not be used.

8. Inspection: Contact Public Works Department to schedule pre-backfill inspection.

Please provide 24-hour advance notice. Sub-grade condition, backfill material, compaction equipment and methods will be reviewed. Complete backfill and compaction operations may be inspected.

9. The bottom of trenches in unpaved areas shall be compacted by hand to a point 2 to 6 inches above the top of the utility, using lifts no greater than 4” (loose measurement) in depth, unless otherwise instructed by that utility company, to protect from damage. Place subsequent lifts to complete the trench in layers of uniform thickness which will insure proper compaction, but not greater than 8 inches in depth. Water shall be added, if required by the Public Works Department, or to obtain the optimum moisture content for compaction. Water shall not be added to frozen ground or when the air temperature is 32º F or below.

10. Upon completion of the work, the Permit holder shall be responsible for the cleanup of all the residual construction debris in the work area.

11. STATE HIGHWAYS

If the work is on a state highway, a KDOT permit is required. Permits are obtained at the KDOT District 6 office at 121 N. Campus Drive. The City must sign the KDOT permit.

12. TEMPORARY TRAFFIC CONTROL (Barricades, Warning Signs, and Lights)

Temporary traffic control is the responsibility of the permit holder/contractor. The permit holder/contractor shall submit a plan to the Public Works Department for review. The temporary traffic control shall conform to Part 6, Temporary Traffic Control, of the latest edition of the Manual of Uniform Traffic Control Devices (MUTCD).

2. SURFACE RESTORATION

A. General

1. Inspections:

a. Prepaving Inspection: Contact the Public Works Department to schedule a prepaving

inspection. Final pavement cut, subgrade preparation and paving equipment and

methods will be reviewed at the prepavement inspection.

b. Paving observations: Immediately upon ordering paving materials notify the Public

Works Department of estimated delivery time. Permit holder is not required to wait

for the Inspector to commence placement.

2. Final Paving Cut: Cut shall have straight edges and rectangular shape. The cut in the

asphalt or concrete shall be a vertical saw cut to full depth or 6 inches. On pavements

greater than six inches, the remainder of the depth may be cut with an air hammer. Gravel

surfaces may be cut by backhoe and shall be cut as near vertical as possible. To create a

bridging effect onto undisturbed soil, the asphalt and concrete pavements shall be cut back

a minimum of 12 inches from the edge of the excavation made into the subgrade. Concrete

pavement patching shall be half panel or full panel in size, with square corners. Tie bars

and dowels are required on concrete surfaced streets and alleys. Minimum of ½ inch tie

bars shall be placed at 24-inch centers on patch edges perpendicular to the direction of

traffic. Dowels may be required if patch covers more than one panel. Use ¾” smooth

steel bars with dowel cap on one end.

3. Pavement Type: The Permit holder shall use the City’s concrete mix for all surface patches

except, on brick streets, or where otherwise specifically permitted. Edges shall be made

to match the adjacent, existing pavement. Patching of brick streets shall be accomplished

per Section I.2.D. The thickness of the concrete patch surface shall be at least as thick as

the adjacent concrete or asphalt surfacing, but not less than 7 inches thick. Asphalt

patching, if allowed, shall be at least as thick as the existing, but not less than 7” thick.

B. Alley or Gravel Surfaces

Material shall meet the existing surface and be of the same type. If the existing material has

a high amount of plastic, clays, trash, and construction debris or is wet or frozen material,

the permit holder shall import new approved material. The compaction of the surface shall

be to the satisfaction of the City Inspector.

C. Concrete Patching

Concrete shall meet the requirements of City Standard Specifications, Section Str-4,

Concrete Pavement, and Section Str-5, Patching.

Page 10: GENERAL IMPROVEMENTS HANDBOOK - Garden City

D. Brick Pavement Patching

1. The Permit Holder shall exercise care in removing paving bricks for reuse in patching.

The City may furnish additional replacement brick, at no cost, for damaged bricks.

2. Concrete Base: Base shall be a minimum of 6” thick; shall meet the requirements of

City Standard Specifications, Section Str-4, Concrete Pavement, and Section Str-5,

Patching. Requirements for placing, consolidating, curing and finishing concrete

pavement shall apply, except a float finish may be used.

3. Cushion: Place a ½” to 1” sand cushion over the concrete base. Set the bricks with

tightly butted joints; seat against adjacent bricks and into the sand cushion with a

rubber mallet.

4. Joints: Fill the joints with dry fine sand. Work the sand into place using a plate

vibrator. Place sufficient sand over the brick so that the units are not in direct contact

with the plate vibrator to reduce the possibility of chipping the brick.

E. Handicap Ramps

The Permit holder shall be responsible for constructing handicap ramps if the permitted

work requires curb and gutter repair UorU reconstruction within 100 feet of a corner location

where a handicap ramp is required. Contact the Public Works Department or Inspector for

specific requirements.

F. Landscaped areas and easements on private property

Any disturbance or damage to landscaped areas of public right-of-way, and the adjacent

impacted area, including easements on private property, caused by the activities of a permit

holder or any agent, affiliate, employee, or subcontractor, while occupying, installing,

repairing or maintaining facilities in a public right-of-way shall be returned or restored to

its functional equivalence before the damage pursuant to the reasonable requirements and

specifications of the City. If the permit holder fails to make the repairs required by the City,

the City may make those repairs and charge the actual repair costs to the permit holder.

3. FIELD QUALITY CONTROL

The provisions of this section shall apply when the concrete patch is 16 cubic yards or greater.

A. The Permit holder shall provide the City with a copy of the Ready Mix Company’s batch

ticket for the concrete delivered to the job site. The Permit holder shall provide the City

with a copy of test results of testing done on the job site, if any.

B. The Permit holder shall provide 3, 7 and 28 day concrete cylinder break test results, unless

otherwise specified. Test cylinders shall be made in accordance with ACI 301. A slump

test will be taken for each set of test cylinders.

A. Cleaning: After paving is complete and sufficiently set to resist sweeping operations, clean

all areas soiled by construction.

B. Guarantee: The Permit holder shall guarantee materials and work performed on street or

alley patches for a period of one year from the date of completion. The Permit holder shall

promptly make such corrections as may be necessary by reason of such defects including the

repairs of any damage to other parts of the system resulting from such defects. The City will

give notice of observed defects with reasonable promptness within the warranty period. In

the event that the Permit holder fails to make such repairs, the City may do so and charge the

Permit holder or the Permit holder’s surety for the cost thereby incurred.

5. ALTERNATES

The Public Works Department may vary or waive any of these specifications, in writing, for the

following instances:

A. Strict conformance to specification presents a safety or health hazard.

B. Emergency conditions exist; such as weather extremes, supply disruptions, or other acts that

could not have been reasonably anticipated and cannot be mitigated by the Permit holder.

C. These specifications are general standards and any deviations will be required to be

submitted to the City for review and approval.

Standards for Placement of

Utilities in

Public Rights-of -Way

1. UNDERGROUND FACILITIES.

In those areas and portions of the city where either the transmission and distribution facilities of

the public utility providing telecommunications or video service, or those of the city providing

electric service are underground, or may hereafter be placed underground, pursuant to Chapter

90 of the Code of Ordinances, then the service provider shall likewise construct, operate and

maintain all of its transmission, amplification and distribution facilities underground.

2. ALLEYS

The typical placement of underground utilities in alleys is shown on Drawing No. III-1.

Underground service drops shall cross alleys within 10° of perpendicular. Service drops crossing

alleys shall be installed in conduit, to allow minimal disruption of other utilities and alley

surfacing during future replacement and/or repairs.

3. OVERHEAD UTILITY INSTALLATIONS

The minimum vertical clearance and separation of overhead utilities crossing or running parallel

with streets and alleys is shown on Drawing No. III-2. Service drops crossing streets and alleys

shall be subject to the same minimum vertical clearance.

4. EASEMENTS

The desired placement of underground utilities in public utility easements is the same as for alley

locations as shown on Drawing No. III-1. However, public utility easements vary in width and

location. Public utility easements are found along side lot lines, rear lot lines and front lot lines.

Prior to commencement of construction in areas with public utility easements and no alleys, a

utility coordination meeting will be arranged by the Director of Community Development and/or

the Director of Public Utilities, so that a coordinated plan for all utilities may be developed. Such

plan will be permanently documented and distributed to all utilities.

5. PERMITS

Work requiring any excavation, demolition, patch, stockpile, or other improvement within the

public rights-of-way, shall be in accordance with Section I, Standards for Excavations in Public

Rights-of-Way. An excavation permit shall be obtained from the City Inspection Department.

General Improvements Handbook (2017) Page 37 of 108

Page 39: GENERAL IMPROVEMENTS HANDBOOK - Garden City

6. RESTORATION OF LANDSCAPING

Any disturbance or damage to landscaped areas of public right-of-way, and/or the adjacent impacted area on private property, caused by the activities of a utility or any agent, affiliate, employee, or subcontractor, while occupying, constructing, repairing or maintaining sidewalks and/or driveways on public right-of-way or private property shall be returned or restored to its functional equivalence before the damage pursuant to the reasonable requirements and specifications of the City. If the utility fails to make the repairs required by the City, the City may make those repairs and charge the actual repair costs to the utility.

7. TEMPORARY TRAFFIC CONTROL (Barricades, Warning Signs, and Lights)

Temporary traffic control is the responsibility of the permit holder/contractor. The permit holder/contractor shall submit a plan to the Public Works Department for review. The temporary traffic control shall conform to Part 6, Temporary Traffic Control, of the latest edition of the Manual of Uniform Traffic Control Devices (MUTCD).

8. STATE HIGHWAYS

If the work is on a state highway, a KDOT permit is required. Permits are obtained at the KDOT District 6 office at 121 N. Campus Drive. The City must sign the KDOT permit.

ASPHALT PAVING

SECTION AP-1

1. SCOPE:

The work covered by this section of the specifications consist of furnishing all labor,

equipment, appliances and materials and in performing all operations in connection with

the construction of a bituminous mix meeting the requirements of Hot Mix Asphalt (HMA)

– Commercial Grade Class A (Section 611) mixed in a central plant, and spread and

compacted on a prepared subgrade in accordance with these specifications and in close

conformity with the lines, grades, thickness and typical cross sections as shown on the plans

or established by the Engineer.

2. MATERIALS:

The materials for the plant mix bituminous mat shall meet the requirements for Hot Mix

Asphalt (HMA) – Commercial Grade Class A, Section 611 and Divisions 1100 and 1200.

The Contractor shall submit from an independent testing lab a Design Job Mix Marshall (50

blow) Properties that fit the requirements of the specific job as specified. All tests shall be

furnished to the Engineer 2 weeks before work starts for approval.

3. EQUIPMENT:

All equipment necessary for accomplishing the work required under this section of the

specifications shall be as specified in the latest edition of the Standard Specifications of the

Kansas Department of Transportation.

4. CONSTRUCTION REQUIREMENTS:

PREPARATION OF ASPHALT CEMENT: Asphalt cement shall be heated within a temperature

range of 275º F. to 325º F. at the time of mixing. All material reheated more than 75º F.

above the maximum shown shall be considered overheated and shall be rejected until the

material can be resampled and tested. The acceptance or rejection will be made on the

same requirements as established for the original material. Asphalt cement received from

the refinery at temperature in excess of 325º F. but not exceeding 375º F. may be used.

PREPARATION OF MINERAL AGGREGATE: Each aggregate ingredient shall be heated and

dried at such temperatures that the temperature as recorded in the hot fines bin after

screening shall not exceed 325º F. If the aggregates contain sufficient moisture to cause

General Improvements Handbook (2017) Page 54 of 108

Page 56: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section AP-1-2

foaming in the mixture or their temperature is in excess of 325º F., they shall be removed

from the bins and returned to their respective stockpiles.

The aggregate or aggregates immediately after heating shall be screened into at least three

(3) sizes and conveyed into separate bins ready for batching and mixing with bituminous

material. When the aggregates furnished are of such size and grading that separating into

three bins is impractical, the number of required separations may be reduced to two (2)

with the approval of the Engineer. The efficiency of the screening operation shall be

sufficient to produce, at plant operating capacity, gradations in each of the sizes of heated

and dried aggregates which are uniform and result in the production of a mixture complying

with the limits specified herein.

PREPARATION OF SUBGRADE: When the bituminous mixture is placed on a prepared

subgrade and whether or not a prime cost is designated on the plans, the prepared base or

road surface shall be prepared to meet the following requirements:

a) The subgrade shall be free of all sod, weeds, brush, debris, or other undesirable

material. All subgrade soil shall be uniformly compacted; soft, yielding material

shall be removed and replaced with approved material. The subgrade shall be

dampened prior to placing the concrete, but care shall be exercise to prevent

puddling or muddy conditions.

b) All fill material shall be approved material, placed in successive layers not

exceeding 8 inches in depth for the full width of the subgrade, and compacted to

95% Standard Proctor.

PLACING OF THE MIXTURE: The bituminous mixture shall be spread and finished

reasonably true to crown and grade by the automatically controlled self-propelled

bituminous paver. Bituminous mixtures may be spread and finished by hand methods only

where machine methods are impractical as determined by the Engineer.

The paver shall be operated at a speed which will give the best results for the type of paver

being used and which coordinates satisfactory with the rate of delivery of the mixture to

the paver so as to provide a uniform rate of placement without intermittent operation of

the paver.

All mixed material shall be delivered to the paver in time to permit completion of spreading,

finishing and compaction of the mixture during daylight hours. Night time work on projects

not open to traffic may be permitted when ample lighting and other satisfactory means are

provided.

General Improvements Handbook (2017) Page 55 of 108

Page 57: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section AP-1-3

Bituminous materials spreaders shall be equipped with electronic sensing devices for grade

controls. The device shall be capable of utilizing the stringline, long ski sled, joint matches,

and automatic transverse grade control methods for controlling grades. The long ski sled

shall have a minimum length of 25 feet.

Bituminous mixtures except on leveling courses shall be spread in a placement thickness so

that after rolling the nominal thickness of the completed mat will not exceed two (2) inches

for the surface or top lift and intermediate lifts.

The maximum thickness for lifts may be increased slightly when such increase is more

adaptable to total pavement thickness and when in the opinion of the Engineer it is not

detrimental to placement and rolling conditions.

If the total plan thickness is less than two and one half (2½) inches the material may be

placed in one lift, unless otherwise designated on the plans.

MACHINE SPREADING: The Engineer will determine a Reference Grade Line necessary to

erect the Reference String Line. On the initial pass the asphaltic mixture shall be spread to

a grade line constant to the Reference String Line. The string will be taut and free from

sags at the time it is in use as a guide for the paver. On the second or subsequent laydowns

the asphaltic mixture shall conform to a Mobile String Line. If the existing surface is of

acceptable centerline grade as determined by the Engineer from the profile survey, the

Engineer may permit the rise of the Mobile String Line for all lifts.

COMPACTION OF MIXTURES: After spreading and strike-off and as soon as the mix

conditions permit the rolling to be performed without excessive shoving or tearing, the

mixture shall be thoroughly and uniformly compacted.

Rollers shall be of the steel wheel and/or pneumatic tire and shall be in good condition,

capable of reversing without backlash and shall be operated at speeds slow enough to avoid

displacement of the bituminous mixture. The use of equipment which results in excessive

crushing of the aggregate will not be permitted. The selection of the type of roller to be

used on the breakdown rolling may be varied to suit mix characteristics. The final rolling of

the top or surface course shall be accomplished with a steel roller unless otherwise

designated.

Any mixture that becomes loose, broken, mixed with foreign material, or which is in any

way defective in finish or density, or which does not comply in all other respects with the

requirements of the specifications shall be removed, replaced with suitable material, and

finished in accordance with these specifications.

CONTACT SURFACES: Contact surfaces of curbing, gutters, manholes, and similar structures

shall be tacked with a thin uniform coating SS-1H. The bituminous mixture shall be placed

General Improvements Handbook (2017) Page 56 of 108

Page 58: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section AP-1-4

uniformly high near the contact surfaces so that after compaction it will be one-fourth (¼)

inch above the edge of such structures.

JOINTS: Joints between old and new pavements or between successive days work shall be

made so as to insure thorough and continuous bond between the old and new mixtures.

Transverse construction joints in previously laid material may be constructed by cutting the

material back its full depth so as to expose a fresh surface. Where a wooden header is used

at a construction joint the cutting may be omitted provided the joint conforms to the

specified thickness and cross section.

Before placing the fresh mixture against a cut joint or against old pavement the contact

surface shall be sprayed or painted with a thin uniform coat of asphalt material. Where a

finishing machine is used, the longitudinal joint shall be made by overlapping the screed on

the previously laid material for a width of at least one (1) inch and depositing a sufficient

amount of mixture so that the joint formed will be smooth and tight.

TACK COAT: A tack coat of SS-1H applied at a minimum of 0.05 gallon per yard will be

placed between lifts

SURFACE TOLERANCES: The surface shall be tested using a sixteen (16) foot straight-edge

at selected locations. The variation of the surface from the testing edge of the straightedge

between any two (2) contacts with the surface shall at no point exceed 1/4 inch. All humps

or depressions exceeding this tolerance shall be corrected by removing defective work and

replacing it with new material as directed. The material required to correct surface

tolerances will be at the expense of the contractor.

WEATHER LIMITATIONS: Hot asphalt pavement shall be placed only when the air

temperature is 50º F. or above and when the weather is not foggy or rainy and when the

surface is free from moisture.

2. PLACING

At the Contractor’s option, the slip form or fixed form paving method may be used.

a. Slip Form Paving.

The contractor may use standard manufacture, slip form paving equipment capable of spreading, consolidating, screeding and float finishing freshly placed concrete

in one pass. Such equipment shall be capable of producing a homogeneous

pavement to the specified cross-section, profile and density, and shall be automatically controlled in regard to line and grade.

Moisten dry subgrade to minimize absorption of water from the fresh concrete.

Subgrade shall not be muddy, soft, frozen, or covered with standing water when concrete is placed.

Use a standard manufacture longitudinal finisher capable of producing a smooth surface to the specified cross-section. The longitudinal finisher may operate either mechanically or manually. Adjust and operate the longitudinal finisher (in conjunction with the finishing screed) so that a small roll of mortar is carried ahead of the float.

b. Fixed Form Paving.

(1) Forms. Use straight, metal forms having adequate strength to support the equipment. Each section shall be a minimum of 10 feet in length. Use forms

with a depth equal to the prescribed edge thickness of the concrete, a base width at least equal to the depth of the forms and without a horizontal joint. Flexible or curved forms must be approved by the Engineer. The Engineer may approve the

use of wood forms in areas requiring hand finishing. Secure the forms in place to withstand the impact and vibration of the consolidating and finishing equipment without visible spring or settlement. Extend flange braces outward

on the base a minimum of ⅔ the height of the form. Remove forms with battered top surfaces or bent, twisted or broken forms. Do not use repaired forms until they have been inspected and approved by the Engineer. Do not vary the top face of

the form from a true plane more than ⅛ inch in 10 feet, and do not vary the vertical face of the form by more than ¼ inch. The forms shall contain provisions for

locking the ends of abutting form sections together tightly, and for secure setting.

(2) Base Support. Provide a foundation under the forms that is compact and true to the specified grade so that the whole length of the form will be set firmly in contact with the grade.

(3) Form Setting. Set forms sufficiently in advance of the point where concrete is being placed so that line and grade may be checked. After the forms have been

correctly set, thoroughly tamp the grade mechanically at both the inside and

General Improvements Handbook (2017) Page 59 of 108

Page 61: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section Str-4-3

outside edges of the base of the forms. Tightly lock form sections, free from play

or movement in any direction. Do not deviate the form from true line by more than ¼ inch at any point. No excessive settlement or springing of forms under the

finishing machine is permitted. Clean and oil forms before the placing of concrete.

(4) Grade and Alignment. Check the alignment and grade elevations of the forms immediately before placing the concrete and make any necessary

corrections. When any form has been disturbed or any grade has become

unstable, reset and recheck the form.

(5) Placing & Finishing. Use an approved roller or razor finishing screed

capable of finishing the pavement to the required grade, section and density.

Operate the finishing screed so that a small roll of mortar is carried ahead of the screed.

(6) Removing Forms. Unless otherwise provided, do not remove forms from

freshly placed concrete until it has set for a minimum of 12 hours, except auxiliary forms used temporarily in widened areas. Remove forms carefully to avoid damage to the pavement.

3. TEXTURING

a. Burlap Drag. Use a drag consisting of a seamless strip of damp burlap, artificial

turf or cotton fabric. Use a drag that produces a uniform, gritty texture when pulled longitudinally along the full width of the pavement. Use only drags that are clean and free of encrusted mortar.

b. Grooving Equipment. Use standard manufacture transverse or longitudinal grooving equipment capable of covering the width of the pavement in a single

pass. Use grooving equipment with a metal comb that is capable of producing a uniform pattern of grooves approximately 3/16 inch wide, spaced at ¾ inch centers and ⅛ to ¼ inch deep. Small or irregular areas may be grooved by hand

methods.

a. Before final finishing is completed and before the concrete has taken its initial

set, the edges of the slab shall be carefully finished with an edger.

b. Float Finish: After the surface stiffens enough to support the operation, float

with hand floats or powered disc floater. Check the concrete surface to insure level and smoothness, cutting down high spots and filling in low areas.

General Improvements Handbook (2017) Page 60 of 108

Page 62: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section Str-4-4

c. Broom Finish: Immediately after the concrete has received a float finish,

produce a coarse transverse scored texture by drawing a concrete broom across the surface. Striations shall be perpendicular to the direction of traffic.

d. With jointer or saw, cut control joints to ¼ of the depth of the slab. Consult the City Engineer for joint spacing requirements. Where control joints meet, they

shall not form tees or angles of less than 70º. Where tees or reentrant corners are unavoidable, a 4-foot length of #4 rebar shall be embedded in the top half

of the slab as a crack stop.

4. CURING AND PROTECTION

a. Protection from Mechanical Injury: During the curing period, the concrete shall be protected from damaging mechanical disturbances, such as load stresses,

heavy shock, and excessive vibration. All finished concrete surfaces shall be protected from damage caused by construction equipment or materials, application of curing procedures, pedestrian traffic, rain or running water.

Concrete injured by any of the above actions shall be removed and replaced at the expense of the Permit holder.

b. Cold Weather Placement: When placing concrete after the first frost or when the mean daily temperatures are below 40º F, the following requirements apply. Use a specified accelerator in the concrete. Maintain concrete temperature at a minimum of 55º F for not less than the time required for the duration of barricade placement. Do not place concrete without approval of the City Engineer on days when the temperature at 9:00 a.m. is below 30º F. Do not place concrete until the outside air temperature is 35º F and rising and stop pouring when the temperature reaches 40º F and is falling. When concrete has been placed and the temperature may drop below 35º F, spread insulated curing blankets over the concrete to prevent freezing of the concrete. These blankets should be left on at least 2 days to assure proper curing, if the

temperatures remain below 40º F. Concrete injured by frost action shall be removed and replaced at the expense of the Permit holder.

c. Hot Weather Placement: When air temperature is expected to exceed 95º F,

the Permit holder shall use hot weather placement procedures in placing,

finishing, protecting, and curing the concrete. The temperature of the concrete at the time of placement shall not exceed 90º F. Provide protection to prevent rapid drying. Start finishing and curing as soon as possible. Water reducing

retarding admixture may be used.

d. Use white pigmented, wax-resin based curing compound, ASTM C309, Type II, Class B, if required by the City Engineer.

1.04 INSTALLATION

A. GENERAL

The pipe shall be installed with a minimum of 4.0 feet of cover from final grade and pipe

shall be installed in accordance with ANSI/AWWA C600 or C605 and the manufacturer's recommendations for installing the type of pipe used unless modified or changed in the

Special Provisions. The Contractor shall provide all tools and equipment including any

special tools designed for installing each particular type of pipe used. Bedding under the pipe is required if the installation is in rock. Vertical separation between watermains and

sanitary sewer forcemains shall be 24” with the forcemain always below the watermain.

B. DEWATERING OF TRENCH

Where water is encountered in the trench, it shall be removed during pipe laying operations and the trench so maintained until the ends of the pipe are sealed and provisions are made to prevent floating of the pipe.

C. RESPONSIBILITY FOR MATERIAL

The Contractor shall be responsible for all material furnished by him and shall replace at his own expense all such material found defective in manufacture or damaged in handling

after delivery by the manufacturer. This shall include the furnishing of all materials and labor required for the placement of installed material discovered damaged or defective prior to the final acceptance of the work, or during the guarantee period.

The Contractor shall be responsible for the safe and proper storage of material furnished by him or to him and accepted by him, and intended for the work, until it has been incorporated in the completed project. The interior of all pipe and other accessories shall be kept free from dirt and foreign matter at all times.

Precautions shall be taken to protect pipe interiors, fittings, and valves against contamination. Pipe delivered for construction shall be strung so as to minimize entrance

of foreign material. When pipe laying is not in progress, as, for example, at the close of the day's work, all openings in the pipeline shall be closed by water-tight plugs. Joints of all pipe in the trench shall be completed before work is stopped. If water accumulates in

the trench, the plugs shall remain in place until the trench is dry.

D. HANDLING OF PIPE:

All pipe furnished by the Contractor shall be delivered and distributed at the site by the Contractor. Pipe, fittings, specials, valves and accessories shall be loaded and unloaded by lifting with hoists or skidding so as to avoid shock or damage. Under no circumstances

shall such materials be dropped. Pipe handled on skidways shall not be skidded or rolled

against pipe already on the ground.

General Improvements Handbook (2017) Page 74 of 108

Page 76: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section W-1-9

In distributing the material at the site of the work, each piece shall be unloaded opposite or near the place where it is to be laid in the trench.

Pipe shall be so handled that the coating and lining will not be damaged. If, however, any

part of the coating or lining is damaged, the repair shall be made by the Contractor, at his expense, in a manner satisfactory to the Engineer.

E. LAYING OF PIPE

Before installation, the pipe and pipe coating shall be inspected for defects. Any damage

to pipe coatings shall be repaired with the same materials used for the original coating

before laying the pipe.

All pipe shall be laid and maintained to the required lines and grades with fittings and valves

at the required locations.

Wherever obstructions not shown on the plans are encountered during the progress of the work and interfere to such an extent that an alteration in the plan is required, the Engineer shall have the authority to change the plans and order a deviation from the line and grade

or arrange with the owners of the structures for the removal, relocation and reconstruction of the obstructions.

Proper implements, tools and facilities satisfactory to the Engineer shall be provided and used by the Contractor for the safe and convenient prosecution of the work. All pipe, fittings and valves shall be carefully lowered into the trench piece by piece by suitable tools or equipment, in such a manner as to prevent damage to pipe materials and protective coatings and linings. Under no circumstances shall materials be dropped or dumped into the trench.

Every precaution shall be taken to prevent foreign material from entering the pipe while it is being placed in the line. During laying operations, no debris, tools, clothing or other

materials shall be placed in the pipe. At times when pipe laying is not in progress, the open ends of the pipe shall be closed by a water-tight plug or other means approved by the

Engineer.

Long radius curves, either horizontal or vertical, may by laid with standard pipe by deflections at the joints. If the pipe is shown curved on the plans and no special fittings are

shown, the curves can be made by deflection of the joints with standard lengths of pipe.

Where field conditions require deflection or curves not anticipated by the plans, the Engineer will determine the methods to be used. No additional payment will be made for

laying pipe on curves as shown on the plans, nor for field changes involving standard lengths of pipe deflected at the joints.

Maximum deflections at pipe joints shall not exceed the applicable specifications of AWWA

or recommendations of the manufacturer. When rubber gasketed pipe is laid on a curve,

General Improvements Handbook (2017) Page 75 of 108

Page 77: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section W-1-10

the pipe shall be jointed in a straight alignment and then deflected to the curved alignment. Trenches shall be made wider on curves for this purpose.

Pipe restraint shall be applied at all tees, Plugs, caps and at bends deflecting 11-1/4� or

more, or movement shall be prevented by attaching suitable tie rods or straps as approved

by the Engineer. Poured concrete blocking shall be placed between solid ground and the fitting; the area of bearing on the pipe and on the ground shall be as shown on Standard

Drawings. The blocking shall be so placed that the pipe and fitting joints will be accessible

for repair.

The cutting of pipe for inserting valves or fittings or shall be done in a neat and workmanlike

manner without damage to the pipe or coating and so as to leave a smooth end at right

angles to the axis of the pipe. Torch cutting of pipe shall not be allowed.

1.05 PIPE JOINTING

A. RUBBER GASKET "PUSH-ON" JOINTS

Jointing of pipe with a rubber gasket "push-on" joint shall be as recommended by the

manufacturer. The rubber gasket and gasket seat inside the bell shall be wiped clean with a cloth. A thin film of lubricant, furnished with the pipe, shall be applied to the inside surface of the gasket. The plain end of the adjoining pipe shall be wiped clean and inserted into the bell a sufficient distance to make contact with the gasket. The plain end shall then be forced "home" by the use of a crow bar, fork tool, or jack assembly.

B. MECHANICAL JOINTS

The inside of the bell and the outside of the spigot of the mechanical joint fittings shall be

brushed thoroughly with a wire brush to remove all loose rust or other foreign material and the cleaned surfaces shall be brushed with soapy water just prior to slipping the gasket over the spigot end and into the bell.

The spigot end of the pipe or fitting shall be accurately centered in the bell before jointing

is begun. After the gasket is in place the gland shall be brought up toward the pipe flange evenly, maintaining approximately the same distance between the gland and the face of

the flange at all points around the socket. Bolts shall be partially tightened alternately

around the socket maintaining approximately equal tension until the final tension is reached. The normal range of bolt torques to be applied to the bolts in the joints shall be

as follows:

Bolt Size Range of Torque (inch) (ft. lb.) 5/8 40 - 60 ¾ 60 - 90 1 70 - 100 1-1/4 90 - 120 Torque loads may be applied with torque measuring or indicating wrenches, or they may be applied using regular socket wrenches, and checked by torque wrenches.

General Improvements Handbook (2017) Page 76 of 108

Page 78: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section W-1-11

If effective sealing is not attained at the maximum torque indicated above, the joint shall

be disassembled and reassembled after thorough cleaning. Overstressing of bolts to

compensate for poor installation practice will not be permitted.

C. CONNECTIONS TO EXISTING MAINS

All connections to watermains in use shall be made by the Contractor unless otherwise

provided in the Plans or Special Provisions. The Contractor shall furnish the fittings and all other materials required. The Contractor shall make all necessary excavations, to

assure gradual transition between the new and existing water main, and all backfilling.

The Water Superintendent and the Contractor shall coordinate the interruptions of service and notification of customers affected.

1.06 TESTING

A. PRESSURE TEST

After the pipe has been laid, all newly laid pipe or any valved section thereof shall be subjected to a hydrostatic pressure of at least 150% the working pressure at the point of testing or 150 psi, whichever is greater. A passing pressure test shall be defined as the maintaining pressure within five (5) psi of the specified test pressure for 2 hours after the air in the pipeline has been expelled and the pipe has been filled with water.

Any damaged or defective pipe, fittings, valves, or hydrants that are discovered following

the pressure test shall be repaired or replaced with sound material and the test shall be repeated until it is satisfactory to the Engineer.

B. LEAKAGE TEST

A leakage test shall be conducted concurrently with the pressure test. Leakage shall be

defined as the quantity of water that must be supplied into the newly laid pipe, or section thereof, to maintain pressure within five (5) psi of the specified test pressure after the air in the pipeline has been expelled and the pipe has been filled with water. If the leakage test is performed independent from the pressure test, the test duration shall be 2 hours.

No pipe installation, or segment thereof, will be accepted if the leakage is greater than that determined by the following formula:

L = SD (P)1/2

148,000

Where: L = allowable leakage, gal/hour

S = length of pipe being tested, feet

D = nominal diameter of pipe, inches

P = average test pressure during test, psi

General Improvements Handbook (2017) Page 77 of 108

Page 79: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section W-1-12

The formula is based upon an allowable leakage of 10.5 gpd/mi/in of nominal pipe diameter.

When testing against closed metal seated valves, an additional leakage per closed valve

of 0.0078 gal/hour/inch of nominal valve size is allowed.

Any damaged or defective pipe, fittings, valves, or hydrants that are discovered following the leakage test shall be repaired or replaced with sound material and the test shall be

repeated until it is satisfactory to the Engineer.

1.07 DISINFECTING WATER MAINS

A. DISINFECTION

Disinfection methods shall be in accordance with AWWA C651. When the disinfecting of

water mains is not to be done by the Contractor, the Contractor shall coordinate such work with the Engineer.

B. PRELIMINARY FLUSHING

The main shall be flushed prior to disinfection, except when the tablet method is used. No site for flushing should be chosen unless it has been determined that drainage is adequate at that site. The flushing velocity shall not be less than 2.5 ft/sec. With 40 psi residual

pressure, a 2-1/2" hydrant outlet nozzle will discharge approximately 1,000 gpm and a 4-1/2" hydrant nozzle will discharge approximately 2,500 gpm.

C. FORM OF CHLORINE FOR DISINFECTION

The most common forms of chlorine used in the disinfecting solutions are calcium

hypochlorite granules or tablets and sodium hypochlorite solutions. The hypochlorite solutions shall be applied to the water main with a gasoline or electrically-powered chemical feed pump designed for feeding chlorine solutions. For small applications the

solutions may be fed with a hand pump, for example, a hydraulic test pump. Feed lines shall be of such material and strength as to withstand safely the maximum pressures that may be created by the pumps. All connections shall be checked for tightness before the

hypochlorite solution is applied to the main.

(a) CALCIUM HYPOCHLORITE. Calcium hypochlorite contains 65 percent (65%) available chlorine by weight. A chlorine-water solution is prepared by dissolving the granules in water in the proportion requisite for the desired concentration.

(b) SODIUM HYPOCHLORITE. Sodium hypochlorite is supplied in strengths from 5.25 to 16 percent available chlorine in liquid form. The chlorine-water solution is

prepared by adding hypochlorite to water.

General Improvements Handbook (2017) Page 78 of 108

Page 80: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section W-1-13

D. METHODS OF CHLORINE APPLICATION:

During the application of any form of chlorine, prevent the treatment dosage from flowing

back into the line supplying the water.

(a) CONTINUOUS FEED METHOD. This method is suitable for general application.

(1) Water from the existing distribution system or other approved sources of supply

shall be made to flow at a constant, measured rate into the newly-laid pipeline. The water shall receive a dose of chlorine at a constant, measured rate. The

two rates shall be proportioned so that the chlorine concentration in the water

in the pipe is maintained at a minimum of 25 mg/l available chlorine for 24 hours, during which time all valves and hydrants in the section treated shall be

operated in order to disinfect the appurtenances. At the end of this 24-hour

period, the treated water shall contain no less than 10 mg/l chlorine throughout the length of the main. After flushing the lines will be ready for use for potable water supply purposes.

Amounts of either a 10 percent sodium hypochlorite solution or 65 percent high test hypochlorite powder required per 500 feet of water line for a 25 mg/l chlorine content

Pipe Size Ounces 10% Solution Ounces 65% Compound 4” 13.1 1.7 6” 26.2 3.8 8” 43.8 6.7 12” 96.3 15.1

(b) SLUG METHOD. This method is suitable for use with mains of large diameter for

which, because of the volumes of water involved, the continuous feed method is not practical.

(1) Water from the existing distribution system or other approved sources of supply

shall be made to flow at a constant, measured rate into the newly-laid pipeline.

The water shall receive a dose of chlorine, also fed at a constant, measured

rate. The two rates shall be proportioned so that the concentration in the water

entering the pipeline is maintained at no less than 300 mg/l. The chlorine shall

be applied continuously and for a sufficient period to develop a solid column or

"slug" of chlorinated water that will, as it passed along the line, expose all

interior surfaces to a concentration of at least 300 mg/l for at least at least

three (3) hours. The application shall be checked at a tap near the upstream

end of the line by chlorine residual measurements.

(2) As the chlorinated water flows past tees and crosses, related valves and

hydrants shall be operated so as to disinfect appurtenances.

General Improvements Handbook (2017) Page 79 of 108

Page 81: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section W-1-14

(c) TABLET METHOD. Tablet disinfection is best suited to short extensions (up to 3,500 feet) and smaller diameter mains (up to 12 inches). Because the preliminary

flushing step must be eliminated, this method shall be used only when scrupulous

cleanliness has been exercised. Tablet disinfection shall not be used if trench water or foreign material has entered the main during construction.

(1) PLACEMENT OF TABLETS. Tablets are placed in each section of pipe and

also in hydrants, hydrant branches, and other appurtenances. They shall be

attached by an adhesive, except for the tablets placed in hydrants and in the

joints between the pipe sections. All the tablets within the main must be at the

top of the main. If the tablets are fastened before the pipe section is placed in

the trench, their position should be marked on the section to assure that there

will be no rotation. In placing tablets in joints, they are crushed and placed on

the inside annular space, or, if the type of assembly does not permit, they are

rubbed like chalk on the butt ends of the sections to coat them with calcium

hypochlorite.

Number of 5 g Calcium Hypochlorite Tablets Required for a dose of 25 mg/l (3.25 g chlorine/tablet) Length of Pipe Joint

Pipe Size 13’ 18’ 20’ 30’ 40’ 4” 1 1 1 1 1 6” 1 1 1 2 2 8” 1 2 2 3 4 12” 3 4 4 6 7

(2) FILLING AND CONTACT. When installation has been completed, the main

shall be slowly filled with water, at a velocity of less than one-foot/second. This

water shall remain in the pipe for at least 24 hours. If the water temperature is

below 41° F, the water shall remain in the pipes for 48 hours.

E. FINAL FLUSHING

After the applicable retention period and confirmation residual testing, with a residual of not less than 10 mg/l, the heavily chlorinated water shall be flushed from the main until the

chlorine concentration in the water leaving the main is no higher than that generally

prevailing in the system, or less than one mg/l. Chlorine residual determination shall be made to ascertain that the heavily chlorinated water has been removed from the pipeline.

F. DISINFECTION AFTER CUTTING INTO OR REPAIRING EXISTING MAINS

The procedures outlined in this section apply primarily when mains are wholly or partially dewatered. Leaks or breaks that are repaired with clamping devices while the mains remain full of water under pressure present little danger of contamination and require no

disinfection.

General Improvements Handbook (2017) Page 80 of 108

Page 82: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section W-1-15

(a) TRENCH "TREATMENT". When an old line is opened, either by accident or by design, the excavation will likely be wet and badly contaminated from nearby

sewers. Liberal quantities of hypochlorite applied to open trench areas will lessen

the danger from such pollution. Tablets have the advantage in such a situation because they dissolve slowly and continue to release hypochlorite as water is

pumped from the excavation.

(b) MAIN DISINFECTION

(1) SWABBING WITH HYPOCHLORITE SOLUTION. The interior of all pipe and

fittings used in making the repair (particularly couplings and tapping sleeves)

shall be swabbed with a five percent (5%) hypochlorite solution before they are

installed.

(2) FLUSHING. Thorough flushing is the most practical means of removing

contamination introduced during repairs. If valve and hydrant locations permit,

flushing from both directions is recommended. Flushing shall be started as

soon as the repairs are completed and continued until discolored water is

eliminated.

(3) SLUG METHOD. Where practicable, in addition to SWABBING WITH

HYPOCHLORITE SOLUTION, a section of main in which the break is located shall be isolated all service connections shut off, and the section flushed and chlorinated as described in Section 4(b) above, except that the dose may be

increased to as much as 500 mg/l, and the contact time reduced to as little as one-half hour. After chlorination, flushing shall be resumed and continued until discolored water is eliminated.

(c) SAMPLING. Bacteriologic samples shall be taken after repairs to provide a record by which the effectiveness of the procedures used can be determined. If the

direction of flow is unknown, samples shall be taken on each side of the main break.

1.08 SEPARATION OF WATERMAINS AND SEWERLINES/POLLUTION SOURCES

A minimum distance of 25 feet shall be maintained between all potable water lines and all septic tanks, waste stabilization ponds or open sewage discharge locations.

Under no circumstances shall a water line extend through a septic tank tile absorption field, or feedlot. All water lines shall be located a minimum of 25 feet from the farthest known extent of any sewage absorption.

A minimum horizontal distance of 10 feet shall be maintained between parallel water and sewer lines. The laying of potable water lines and sanitary sewers shall be in separate trenches with undisturbed earth between them. If the 10 foot horizontal separation distance between a proposed waterline and sewerline cannot be maintained the engineer

General Improvements Handbook (2017) Page 81 of 108

Page 83: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section W-1-16

shall contact KDHE and additional protection shall be determined on a case by case basis.

When a water pipe and a sanitary sewer cross and the sewer is 2 feet or more (clear space) below the water pipe, no special requirements or limitations are provided herein. At all other crossings, the sanitary sewer is to be constructed of one of the following materials (or approved equal) and pressure tested to assure water tightness pursuant to Chapter VI of the KDHE Minimum Standards of Design of Water Pollution Control Facilities:

a. Utilize PVC pipe conforming to ASTM D3034 with minimum wall thickness of SDR26, ASTM F679, ASTM F789, or ASTM F794, with gasketed push-on joints in conformance with ASTM D3212. Joints in the sewer pipe shall be located as far as practical from the intersected water line.

b. Utilize ductile iron pipe Class 150 designed in accordance with ANSI/AWWA C150/A21.50 and manufactured in accordance with ANSI/AWWA C151/A21.51, with gasketed push-on joints or mechanical joints. Joints in the sewer pipe shall be located as far as practical from the intersected water line.

Where a water main is laid across or through an area where there is an existing sanitary sewer, which is not constructed of one of the above specified materials and is 2 feet or less below the water pipe, the existing sewer shall be encased in concrete with a minimum of 6 inch thickness for a 10 foot distance on each side of the crossing or the crossed section of sewer requirements.

Under no condition will it be considered that encasement of the water main through an area of real or potential pollution would provide the protection needed to the water supply.

When pressure sewer lines (force mains) run parallel to water lines, the separation distance shall be as far as practical, maintaining a minimum horizontal separation distance of at least 10 ft. There shall be at least 2 ft. vertical separation at crossings with the water main always crossing above the sewer force main.

1.09 CERTIFICATION BY MANUFACTURER

When required by the Engineer, the Contractor shall furnish certification by the manufacturer of the pipe, fittings, valves, hydrants, and other appurtenances to be furnished on this project, certifying that the materials comply with the applicable

specifications.

All pipe shall be clearly marked with type, class and/or thickness as applicable. Lettering shall be legible and permanent under normal conditions of handling and storage.

1.11 SEPARATION FROM WATERMAINS.

A minimum horizontal distance of ten (10) feet shall be maintained between water and sewer

lines. At points where sewers cross water mains, the sewer shall be constructed of cast or ductile

iron, or encased in concrete for a distance of ten (10) feet in each direction of the crossing unless

the water main is at least two (2) feet above the sewer.

When using PVC (SDR-35) pipe and with advance approval by the Engineer, the crossing may be

constructed using a section of pipe centered on the pipe to be crossed, resulting in joints located

the maximum distance from the pipe to be crossed.

1.12 CERTIFICATIONS & TESTING.

A. REPORTS. Certified records of the tests made by the manufacturer or by a reliable

commercial laboratory shall be submitted to the Engineer with each shipment of pipe.

B. VIDEO. Prior to final acceptance, a video (CCTV) inspection shall be conducted by the City

to check for alignment, deflection and other defects.

C. LEAKAGE. Before acceptance, hydrostatic or air pressure tests shall be conducted, by the

contractor in the presence of the Engineer. Testing method(s) to be used will properly consider

groundwater elevation in relation to the sewer.

Infiltration-exfiltration rates exceeding 25 gallons per day per inch of pipe diameter per mile

for any section of the system shall be considered excessive and the section of pipe has failed.

Infiltration-exfiltration tests must be conducted with a minimum of 4’ of static water head

above the invert of the sewer at the upstream manhole. Infiltration-exfiltration shall be less

than 1.14 gallons per day per vertical foot of manhole height.

Low Pressure Air Test: Two procedures are included to find the rate of air leakage -- the

constant-pressure method and the time-pressure drop method. This test may be used as a

preliminary test to show the condition of a buried line prior to final backfill, paving, and other

construction activities.

General Improvements Handbook (2017) Page 94 of 108

Page 96: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section SS-1-7

This test is per Uni-Bell PVC Pipe Association, UNI-B-6-98. The section of the line to be

tested is plugged. Air, at low pressure, is introduced into the plugged line. The line passes

the test if the rate of air loss, as measured by pressure drop, does not exceed a specified amount

in a specified time.

APPARATUS.

Plugs--Mechanical or pneumatic type.

Air Compressor--A properly calibrated portable, oil-free air source with a singular control

panel containing a main shut-off valve, pressure-regulating valve, 9 psig pressure-relief valve,

input pressure gage, and a continuous monitoring pressure gage having a pressure range from

0 psi to at least 10 psi with minimum divisions of 0.10 psi and an accuracy of ± 0.04 psi.

Rotameter, standard CFM reading with an accuracy of ± 2%.

SAFETY PRECAUTIONS.

It is extremely important that the various plugs be properly installed and braced to prevent the

sudden expulsion of a poorly installed or partially inflated plug. Observe the following

minimum safety precautions:

1. No one shall be allowed in the manholes during testing.

2. Install and restrain all caps and plugs securely.

3. It is mandatory that all the caps and plugs be braced as an added safety factor.

4. Do not overpressurize the lines. Do not exceed 9.0 psig. A regulator or relief valve set no

higher than 9 psi shall be included on all pressurizing equipment.

PROCEDURE.

Clean the section of sewer line to be tested by flushing or other means.

Isolate the section of sewer line to be tested by inflatable stoppers or other suitable test plugs.

Plug or cap the ends of all branches, laterals, tees, wyes, and stubs to be included in the test to

prevent air leakage. All plugs and caps shall be securely braced to prevent blow-out. One of

the plugs or caps should have an inlet tap, or other provision for connecting a hose to a portable

air control source.

Connect the air hose to the inlet tap and portable air control source. The air equipment shall

consist of necessary valves and pressure gages to control an oil-free air source and the rate at

which air flows into the test section to enable monitoring of the air pressure within the test

section.

Add air slowly to the test section until the pressure inside the pipe reaches 4.0 psig.

General Improvements Handbook (2017) Page 95 of 108

Page 97: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section SS-1-8

After the pressure of 4.0 psig is obtained, regulate the air supply so that the pressure is

maintained between 3.5 to 4.0 psig for at least 2 min. The pressure will normally drop slightly

until equilibrium is obtained; however, a minimum of 3.5 psig is required.

Determine the rate of air loss by either the constant pressure method or the time-pressure drop

method.

Constant Pressure Method--Add air until the internal air pressure of the sewer line is raised to

4.0 psig and the test pipe section is stabilized. Release the pressure to 3.5 psig to run the

constant pressure test. The air-flow rate in standard cubic feet per minute is read directly by

a rotameter. Convert this air-flow rate to actual cubic feet per minute of air leaking from the

test section by using the absolute pressure and temperature in the test section. The

requirements for air loss under the constant pressure method shall be considered satisfied if

the air loss does not exceed the specified leakage rate in cubic feet per minute per square foot

of internal pipe surface area.

Time-Pressure Drop Method--Air is slowly introduced into the section of pipe to be tested,

until the air pressure is raised to approximately 4.0 psi and the test pipe section is stabilized.

Disconnect the air supply and decrease the pressure to 3.5 psi before starting the test.

Determine the time required for the pressure to drop from 3.5 psi to 2.5 (or 3.0) psi, and

compare this interval to the required time shown in Tables 1 or 2 to decide if the rate of air

loss is within the allowable.

Upon completion of the test, open the bleeder valve and allow all air to escape. Plugs should

not be removed until all air pressure in the test section has been reduced to atmospheric

pressure.

TEST TIME CALCULATIONS.

Calculate all test times by the following formula:

T = 0.085 DK/Q

where:

T = shortest time allowed for the air pressure to drop 1.0 psig, seconds

K = 0.000419 DL but not less than 1.0

Q = leak rate in cubic feet/minute/square feet of internal surface = 0.0015 CFM/SF

D = nominal diameter of sewer pipe, inches

L = length of test section, feet

Table 1 contains the specified minimum times required for a 1.0 psig pressure drop from a

starting pressure of 3.5 psig using a leakage rate of 0.0015 ft3/min/ft2 of internal surface.

General Improvements Handbook (2017) Page 96 of 108

Page 98: GENERAL IMPROVEMENTS HANDBOOK - Garden City

City of Garden City, Kansas 2017 Standard Specifications Section SS-1-9

Table 2 contains the specified minimum times required for a 0.5 psig pressure drop from a

starting pressure of 3.5 psig using a leakage rate of 0.0015 ft3/min/ft2 of internal surface.

This test method is used for testing of long sections or sections of larger diameter pipes.

The total leakage from any test section shall not exceed 625Q.

If the pressure drops 1.0 psig, or 0.5 psig, before the appropriate time shown in Table 1, or

Table 2, has elapsed, the air loss rate shall be considered excessive and the section of pipe

has failed the test.

If lateral or service lines are included in the test, their length may be ignored for computing

required test time if the test time requirements are met. If the test section fails, time shall be

recomputed to include all the lateral lengths using the following formula:

T = 0.085(D12L1 + D2

2L2 + … )/( D1L1 + D2L2 + ... )(K/Q)

where:

T = shortest time allowed for the air pressure to drop 1.0 psig, seconds,

K = 0.000419 (D1L1, + D2L2 + ...), but not less than 1.0,

Q = 0.0015 CFM/SF,

D1,D2,etc. = nominal diameters pipe being tested, and

L1,L2,etc. = respective lengths of the pipes being tested.

If the recomputed test time is short enough to allow the section tested to pass, then the test

section meets the requirements of this test method.

Note – Consult with pipe and appurtenance manufacturer for maximum test pressure for pipe

size greater than 30 in. in diameter.

Note – It is not necessary to hold the test for the entire period of time in Table 1 or Table 2 when

it is evident that the rate of air loss is zero or less than the allowable, and authorized by the

Engineer.

Manhole Vacuum Test: This test is used as an acceptance test for manholes. However, it may be

a preliminary test to enable the Contractor to demonstrate the condition of the manholes prior to

backfill.

PREPARATION OF THE MANHOLE

All lift holes shall be plugged. All pipes entering the manhole shall be temporarily plugged and

securely braced to prevent them from being drawn into the manhole.

PROCEDURE
